Study summary

The POSITION project aims to investigate the cognitive mechanism of postural body awareness as a risk factor for injury and as a target for a primary prevention strategy based on the Resource Optimization of Armed Forces (ROAF) method.

Read the detailed description

Physical activity and sport play an important role in the military environment to develop and optimize the operational capability of warfighters. Nevertheless, the prevalence of injuries is high and the identification of risk factors accessible to primary prevention measures is a major challenge for the protection of warfighter health. Military epidemiologic data show that the majority of injuries are acute fall-type injuries following a loss of balance. These data suggest that the quality of postural balance may influence the occurrence of injuries encountered during military physical activities. The high level of stress to which individuals are exposed during military physical activities could contribute to the degradation of postural balance quality. The POSITION project aims to study the cognitive mechanism of postural body awareness as a risk factor for injury and as a target for a primary prevention strategy based on the Resource Optimization of Armed Forces (ROAF) method. ROAF could improve postural control and decrease the intensity of the psychobiological stress response, and thus reduce the incidence rate of fall injuries occurring during military physical activities.

What researchers measure

Primary outcomes

  1. Incidence rate of imbalance injuries in each of the two groups (ROAF vs active control).

    The primary endpoint will be the incidence rate of imbalance injuries in each of the two groups (ROAF vs active control).

    Time frame: 3 weeks

Secondary outcomes

  1. Evolution of postural awareness measured by the postural awareness scale.

    Evolution of the self-questionnaire measuring postural awareness completed at inclusion, at the final visit and at the beginning of each workshop; 8 times in total.

    Time frame: 3 weeks

  2. Evolution of postural balance

    Difference between postural balance assessed during the inclusion visit and the final visit, using a posturography tool.

    Time frame: 3 weeks

  3. Evolution of the stress level measured by the perceived stress scale

    Evolution of the self-questionnaire measuring perceived stress completed at inclusion, at the final visit, and at the beginning of each workshop; 8 times in total.

    Time frame: 3 weeks

  4. Evolution of the hormonal stress level.

    Difference of levels of hormonal stress in a saliva sample (at the inclusion and final visit).

    Time frame: 3 weeks
